Being rather tall I had the same problems with my seat.
I took the car to a car saddler/upholsterer as we say in Austria.
He replaced the filling of the lateral shoulder bolster by a much softer filling, thus the shape of it remained the same but the material was much more elastic and flexible than the original one - that helped a lot.
The same guy managed to install the 2" seat lowering kit using self-made distance pieces of metal underneath the front part of the seat.....my seat came down more than 2" at the back and for the purpose of thigh support came up more than 2" at the front.
Just perfect.
